Product Overview: 74ACT240TTR from STMicroelectronics

The 74ACT240TTR is a high-speed, advanced CMOS technology octal buffer and line driver designed to interface with 3-state outputs. Manufactured by the renowned semiconductor company, STMicroelectronics, this integrated circuit is part of their 74ACT series, which is well-known for its robust performance and compatibility with TTL (Transistor-Transistor Logic) levels.

This device features eight non-inverting buffers with 3-state outputs, making it an excellent choice for driving bus lines or buffering memory address registers. The 3-state control gate is a common feature, which allows the outputs to assume a high impedance state, effectively disconnecting the device from the bus line, and thus, preventing bus contention.

The 74ACT240TTR comes in a TSSOP (Thin Shrink Small Outline Package) with 20 pins, which is not only space-saving but also conducive to efficient PCB (Printed Circuit Board) design and layout. Its part number suffix, 'TTR', indicates that the device is provided in tape and reel packaging, which is suitable for automated assembly processes used in mass production.

This IC operates over a wide voltage range from 4.5V to 5.5V, making it compatible with 5V systems, and it offers the benefit of a high noise immunity structure. The speed and driving capacity of the 74ACT240TTR make it a versatile choice for a variety of applications, including driving capacitive loads and power conservation in high-speed systems.

Key features of the 74ACT240TTR include:

• Octal non-inverting buffer/line driver with 3-state outputs
• Advanced high-speed CMOS technology
• Operating Voltage Range: 4.5V to 5.5V
• High noise immunity characteristic of CMOS devices
• Improved latch-up immunity
• Low power consumption
• Compatibility with TTL levels
• Available in TSSOP-20 packaging suitable for automated assembly

Overall, the 74ACT240TTR is a reliable and efficient solution for digital systems requiring high-speed data transmission and buffering with minimal power dissipation. Its robust design and advanced features ensure that it remains a popular choice among engineers and designers for a broad range of applications.
